PORTABLE ADJUSTABLE HAY-STACKER.

To all 'whom it may concern:

Be it known that we, GOTHARD HEEDWELL and WILLIAM F. MCNEW, citizens of the United States, residing at Boone, in the county of Boone and State of Iowa, have invented a new and useful Portable Adjustable Hay-Stacker, of which the following is a specication.

The object of this invention is to provide an improved construction for hay stackers or derricks.

Our invention consists in the construction, arrangement and combination of elements hereinafter setforth, pointed out in our claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation showing our improved device in position for practical use. Fig. 2 is a horizontal section on the indicated line 2 2 of Fig. 1. Fig. 3 is an elevation of a part of the device opposite to Fig. 1 and on an enlarged scale, portions being broken away to illustrate interior construction. Fig. 4 is a detail vertical section illustrating the means employed to step the central standard in the base.

In the construction of the apparatus as shown a base is built up of runners 10, 11 rigidly connected by cross-bars 12, 13, posts 14 rising in converging planes from corners of the bottom frame, an upper frame consisting of bars 15, 16, 17, 18 to the corners of which the upper ends of the posts 14 are fixed, and a step bar 19 connecting central portions of the cross-bars 12, 13. The runners 10, 11 and cross-bars 12, 13 preferably are made of tubing, such as gas pipe, and are connected at their ends by side-outlet elbows 20. The side outlets of the elbows are inclined on converging planes and the lower ends of the posts 14 are screwed therein. The posts 14 also preferably are made of tubing. The upper frame bars 15, 16, 17, 18 preferably are made of tubing and are connected at their ends by side-outlet elbows 21. The side outlets of the elbows 21 are inclined on diverging pla-nes and the upper ends of the posts 14 are screwed therein. End portions of the step bar 19 preferably are screwed into the laterals of tees 22, 23

'carried by central portions of the cross-bars 12, 13. A tee 24 (Fig. 4) is carried by the central portion of the step bar 19 and astep block 25 is screwed into the lateral of said tee and projects upwardly therefrom. The step block 25 is formed with a horizontal Specification of Letters Patent.

raceway in its upper portion and a foot block 26 extends within said step block and is formed with a flange 27 overlying said raceway and separated therefrom by bearing balls 28. A central post 29, of tubular form, is provided and the lower end portion of said post embraces and is fixed to the foot block 26. The post 29 is arranged vertically and extends centrally through the upper frame of the base. The post 29 is journaled intermediate of its ends in a bearing 30 located centrally of the upper frame of the base and carried by brackets 31 fixed respectively to the bars 15, 16, 17, 18 and to said bearing. The runners 10, 11 preferably are curved from end to end and are arranged with their convex faces downward (Fig. 1). A ladder 32 is mounted in inclined position and connected at its ends to the cross-bar 13 and bar 18 respectively. An extension member 33 is mounted in and adapted for longitudinal adjustment rela- .tive to and projects at its upper end from the central post `29. The extension member 33 is formed with a plurality of holes 34 in one side adapted to be engaged by teeth of a pinion 35. The pinion 35 is carried by a hand crank shaft 36 journaled in a boxing 37 on the central post 29 and said pinion extends through a slot 38 in said post. The hand crank shaft 36 also carries a ratchet wheel 39 adjacent to the pinion 35 and a gravity pawl 40 is pivoted on and extends through the rim of the box 37 and is adapted to engage said ratchet wheel at one end. The upper end portion of the extension member 33 is forked and a sheave 41 is pivoted therein. A clamp 42 is mounted on and is adjustable vertically of the central post 29 above the upper frame of the base and an arm 43 is fixed to said clamp and projects horizontally therefrom beneath the box 37. A drum shaft 44 is journalcd in the outer end portion of the arm 43 and is formed with a hand crank 45 on one end portion. ratchet wheel 46 adapted to be engaged by a gravity pawl 47 pivoted on the arm 43. A clamp 48 is mounted on and is adjustable vertically of the central post 29 and projects on either side of said post. An arm 49 is fixed to the clamp 48 and projects horizon tally therefrom between the arm 43 and box 37. The outer end portion of the arm 49 is forked and a sheave 50 is pivoted therein. A boom 51 is hinged at one end to the end The drum shaft 44 also carries a portion of the clamp 48 opposite to the arm 49. The boom 51 preferably is formed of tubing and a boom extension 52 is mounted therein and adapted for longitudinal adjustment relative thereto. The boom extension 52 is formed with a plurality of holes 53 (Fig. 3) in one side adapted to be engaged by teeth of a pinion 54. The pinion 54 is mounted on a shaft 55 journaled in a box 56 and extends through a slot 57 in the boom 51. The box 56 preferably is fixed to the central portion of the upper side of the boom 51. The shaft 55 also carries a ratchet wheel 58 adjacent to the pinion 54 and a detent 59 is pivoted to and extends through the rim of the box 56 and is adapted to engage and lock said ratchet wheel. The shaft 5 5 also carries a sprocket wheel 60 which is connected by a chain 61 to a driving sprocket 62 journaled on the heel portion of the boom 51. The driving sprocket 62 is formed with a handle 63 adapted for manual use to rotate said wheel.

A collar 64 is fixed to the outer end portion of the boom extension 52. A cable 65 is fixed at one end to the upper portion of the collar 64, extends through the sheaves 41 and 50 and is fixed at its opposite end to and adapted to be wound on the drum shaft 44. A pulley block 66 is suspended by the lower portion .of the collar 64. A pulley block 67 is suspended by the lower portion of the boom 51. A pulley block 68 is carried by one of the side-outlet elbows 20. A hoisting cable 69 is rove through the pulley blocks 66, 67 and 68 and may be attached to draft power, such as a horse, at its lower end and to hoisting devices, such as a fork or slings, at its upper end. 7e have not illustrated the draft power or hoisting devices (fork or slings) as they form no part of our present invention and may be modified at will. Draft chains 70 are detachably secured by collars 71 to the cross-bar 12 and are adapted to be connected to a draft device, such as a swingletree 72, by means of which the entire derrick or stacker can be hauled from place to place over the ground, the shape of the runners 10, 11 serving to facilitate such transportation.

In practical use of this apparatus the post extension 33 may be adjusted longitudinally by manipulation of the shaft 36 and detent 40; the boom extension 52 may be adjusted longitudinally by manipulation of the driving sprocket 62 and detent 59; the inclination of the boom and boom extension relative to the central post may be adjusted by manipulation of the drum shaft 44, detent 47 and cable 65 and the hoisting lof substance such as hay may be effected through the use of the cable 69, equipped as above described. When the cable 69 is holding a load of substance such as hay suspended near to the pulley block 66, such load may be car- M ried through an arc having the central post 29 as its axis by rotating such post as by a lead line (not shown) extending from the' collar 64 to a convenient point of manipulation. The attachment of the pulley block 68 may be made to any portion of the base frame for convenience in use without reversing or altering the cardinal position of the apparatus.
